It is a bit spectacular how aircraft are ineffective in a modern warfare environment. If you send them in, they get blown out of the sky.
i posted a video from YT-militaryaviationhistory where he interviews Justin Bronk about the air war in UKR.
the rus af has been crippled by lack of practice and actual air time due to underfunding from kleptocracy. even if they were properly funded, he questions if any air force(nato incl) other than the US af/navy is capable of prosecuting a full SEAD campaign. SEAD and DEAD is a specialty that you need to invest in, and many nations haven't seen the need to have the capability much less pay for it in the last 3 decades.
the USAF has its wild weasels and the navy has its growlers, but the only other dedicated sead squadron was/is the RAF and GER tornados(almost 50 years old). f-16 and f-15 can use the HARM but need the ecm pods to do the full role. to some degree the F-35 can give you some SEAD, but probably not the ability to completely dismantle an IADS like the US did in iraq.
but if you do gain air superiority, things like the small diameter bomb will shut down any ground vehicles/arty. as some military commenters on the news have opined, the US could shut down the russian army in less than a week.
